what is a process whereby glaciers mechanically erode the landscape by picking up rock material and carrying it away? plucking Glaciers usually flow at predictable speeds, but when they do advance rapidly, what is it called?
It is an elongated, deep and narrow sea or lake drain amid steep land. Glaciers that are up to 3 km thick curve out fjords usually. Through several ice ages, the glaciers formed this landscape. Gravel and sand deposits from the glaciers made certain areas of the fjord shallower. Fjords are often natural harbours.
Glaciers have carved some of Earth’s most beautiful landscapes by steepening and deepening valleys through erosion. Think of the Scottish Highlands, Yosemite National Park in the US, or the 2011-01-21 · They dig deep into the terrain, forming rugged, dramatic landscapes. As they move, glaciers erode or wear away the land beneath and around them. Glaciers carry great amounts of soil, rock, and clay.
Glaciers usually follow the easiest route down a mountain, which is often an old river valley. Over time rivers slow in their erosion of the geography around them but are never quite done changing the landscape completely. Young rivers erode the rock and soil quickly in order to achieve equilibrium between the altitude of their headwaters and their final expulsion at sea level. Because glaciers are among the earliest geological processes studied by geologists whose studies were in Europe, the terminology applied to glaciers and glacial features contains many terms from European languages. 14.4.1 Erosional Glacial Landforms.

Abrasion erosion of glaciers is when the particles in motion are grinding at the underlying bedrock. The rock particles are frozen to the bed of the ice and erode the underlying sediment similar to sandpaper. This mechanism yields fine sediment and is most effective on soft bedrock.
Next Question > U-shape. Glaciers push through the land leaving a U-shaped valley. Next Question > V-shape.

Young rivers erode the rock and soil quickly in order to achieve equilibrium between the altitude of their headwaters and their final expulsion at sea level. Glaciers primarily erode through plucking and abrasion.
As erosion takes place, the glacial trough becomes wider and deeper. e.g.

Glaciers can shape landscapes through erosion, or the removal of rock and sediment.
Answer: Option C. Explanation: Glaciers are mass form of ice found in the high altitudes. During summer the glaciers melt down and rich source of pure water is obtained. Glaciers erode through two main processes and they are plucking and abrasion. 2018-09-10 · Glaciers shape the land through processes of erosion, weathering, transportation.
